General Description
The MAX270/MAX271 are digitally-programmed, dual
second-order continuous-time lowpass filters. Their typi-
cal dynamic range of 96dB surpasses most switched
capacitor filters which require additional filtering to
remove clock noise. The MAX270/MAX271 are ideal for
anti-aliasing and DAC smoothing applications and can
be cascaded for higher-order responses.
The two filter sections are independently programmable
by either microprocessor (FP) control or pin strapping.
Cutoff frequencies in the 1kHz to 25kHz range can be
selected.
The MAX270 has an on-board, uncommitted op amp,
while the MAX271 has an internal track-and-hold (T/H).
